Process of the
uptake of potentially toxic substances by the body, the
biotransformation they undergo, the distribution of the substances and their metabolites in the tissues,
and the
elimination of the substances and their metabolites from the body. Both the amounts and the concentrations
of the substances and their metabolites are studied. The term has essentially the
same meaning as
pharmacokinetics, but the latter term should be restricted to the study of pharmaceutical substances.
